The medieval University of Dublin (Latin: Universitas Dubliniensis) was an early unsuccessful attempt to establish a university in Dublin, the capital city of the Lordship of Ireland. Founded in 1320, it maintained an intermittent existence for the next two centuries, but it never flourished, and disappeared for good at the Reformation in Ireland (1534–41). It was located in Saint Patrick's Cathedral, Dublin. It had no connection with the present University of Dublin, better known as Trinity College Dublin, which was founded in 1592.[1]
